Quidway AR 28 Series Routers Installation Manual
Chapter 1 Overview
Chapter 1 Overview
1.1 Brief Introduction
Quidway AR 28 Series Routers were independently developed by Huawei
Technologies for use on enterprise-level networks. Depending on the network size,
Quidway AR 28 Series Routers can be either core routers on small and medium
enterprise networks, or access routers for network branches on some large-sized
enterprise networks. Therefore, Quidway AR 28 Series Routers are suitable for the
application on the carrier-level networks, such as telecom management networks and
billing networks.
Quidway AR 28 Series Routers adopt modular design and provide a wide range of
optional MIMs (Multifunctional Interface Modules) and SICs (Smart Interface Cards).
Among all models of the series, the AR 28-10, the AR 28-11, the AR 28-12, the AR
28-13, and the AR 28-14 are available with two types of units: AC-powered and
DC-powered.
Quidway AR 28 Series Routers adopt high speed PowerPC microprocessor and the
VRP (Versatile Routing Platform), a network operation system platform developed by
Huawei Technologies. Besides the benefit of simple configuration, VRP provides rich
network security features, and supports dumb terminal access, SNA (Systems Network
Architecture)/DLSw (Data-Link Switching), IP multicast, and abundant QoS (Quality of
Service) features. Thereby, Quidway AR 28 Series Routers can operate together with
other Quidway series routers and Ethernet switches to provide overall end-to-end
network solutions for clients in industries such as telecommunication, ISP, finance,
taxation, public security, and transportation, medium-and-large-sized enterprises.
Quidway AR 28 Series Routers deliver features of xDSL (Digital Subscriber Line),
MPLS (Multiprotocol Label Switch), NTP (Network Time Protocol). Networked with the
NE Series High-End Routers, the AR 28 series can provide comprehensive solutions
for carriers and large industrial users.
Currently, the AR 28 series include these models:

Quidway AR 28 Series Routers Installation Manual
Chapter 1 Overview
I. High-performance processor
Quidway AR 28 Series Routers use high-performance processors to process all the
integrated interface data. All performance indicators, such as packet processing
capacity, maximum traffic on interfaces, delay, frame drop rate, restoration period due
to overloading of the system and system reset period, can meet users’ requirements.
II. Multiple interface card/interface module options
Quidway AR 28 Series provides SIC slots and MIM slot, where you can install various
types of SICs and MIMs. The available interfaces include synchronous/asynchronous
serial interface, asynchronous serial interface, T1/CT1/PRI interface, E1/CE1/PRI
interface, BRI S/T and U interfaces, Ethernet interface (including FE/GE, electrical
interface and fiber interface), ADSL/G.SHDSL interface, ATM 25M/155M interface,
E3/T3 interface, and so on. The user can change or extend SICs or MIMs as needed.
Thereby, the investment that has been made can be protected to the maximum degree.
III. Multiple channels of asynchronous serial interface access
z
Connected to PSTN (Public Switched Telephone Network) via the asynchronous
serial interface, the router can work as a small Internet access server.
z
With an analog Modem interface card, the router can be directly connected to
PSTN to serve as a small access server.
IV. Ethernet access solution
By extending SICs and MIMs, Quidway AR 28 Series Routers can provide multiple
forms of Ethernet interfaces, such as optical/electrical interface, 10/100/1000Mbps
interface. Thereby, the networking capability of the router can be significantly
improved.
V. Voice capabilities
Quidway AR 28 Series Routers are available with a wide range of voice interface
modules, which can provide such interfaces as FXO/FXS/E&M, E1VI, and T1VI. The
FXS/FXO/E&M interface can connect common phone sets, fax machines and private
branch exchanges (PBXs); the CE1/PRI or CT1/PRI interface can connect the E1 or T1
interface of switches, as well as communicating with the gatekeeper (GK). With
high-speed CPU and digital signal processing (DSP) technology, Quidway AR 28
Series Routers can provide voice over IP (VoIP) and voice over frame relay (VoFR) with
high quality voice. They can drive down the cost of long distance communications
between main office and branches in enterprise deployment.
VI. xDSL/MPLS features
xDSL is a simple but highly-efficient broadband technology that achieves large data
transmission capacity over existing copper wiring by using the digital code modulation
technology. The ADSL/ADSL-I/G.SHDSL module for AR 28 Series allows the
Huawei Technologies Proprietary

Chapter 1 Overview
medium-to-small-sized enterprises to access the Internet over DSLAM equipment via
PSTN.
MPLS, a combination of IP and ATM technologies, replaces the traffic identified by IP
header with a short and length-fixed label, based on which a router makes the
forwarding decision. It can provide faster forwarding speed, get support from IP routed
protocols, and control protocols, thus satisfying the requirements that various new
applications put on the network. MPLS VPN is a VPN technology that implements the
interconnection of private networks via Label Switched Paths (LSPs). As LSP is a
tunnel across the public network on its own, MPLS has an inherent advantage in terms
of VPN implementation. AR 28 Series Routers usually act as Label Edge Routers
(LERs) to implement service classification, label distribution, encapsulation, and
multi-label peel-off by connecting an MPLS domain to a non-MPLS domain or
connecting MPLS domains of different service providers.
VII. Data security
z
Supports ID authentication protocols, including PAP (Password Authentication
Protocol), CHAP (Challenge Handshake Authentication Protocol), RADIUS
(Remote Authentication Dial in User Service), TACACS+.
z
Implements firewall to prevent invasions from external networks.
z
Supports VPN (Virtual Private Network, including GRE, L2TP) and provides IPSec
(IP Security) and IKE (Internet Key Exchange) technologies. Hence, the security
of the user private network in the Internet environment can be guaranteed.
z
Provides backup solutions based on the backup center technology.
VIII. Online software upgrade
512 KB Boot ROM and 32 MB Flash memory provide the user with adequate physical
carrier to upgrade the software online, add new features, and extend new functions
according to market demands.
IX. Chassis
Quidway AR 28 Series Routers adopt integrated structure design. They perform
excellently on heat dissipation, EMC (Electromagnetic Compatibility) and safety.

Note:
z
The SIC slots on the AR 28-11/28-12/28-13/28-14 do not support the
SIC-1FEA/SIC-1ETH card, but two fixed Ethernet interfaces are available on these
models.
z
The AR 28-10 supports only one SIC-1FEA/SIC-1ETH card.
z
Interface cards and modules may be available with multiple versions as the result of
hardware upgrade. To identify the version of a card or module, read the label, for
example, RT-4FXO/RT-4FXO-V2, on the card or module.
z
An interface card (including the silkscreen on its panel) looks the same before and
after hardware upgrade. Upgraded interface cards are functionally backward
compatible and some can even provide enhancements. To support the upgraded
hardware, you need to upgrade host software.

Quidway AR 28 Series Routers Installation Manual
Chapter 3 Installation Preparation
Chapter 3 Installation Preparation
3.1 Requirements on Environment
AR 28 Series must be used indoors. To ensure the normal operation and prolong their
service life, the following requirements for installation site must be met.
3.1.1 Requirements on Temperature/Humidity
Certain requirements on temperature and humidity in the equipment room shall be met.
If the relative humidity is too high, the insulation materials in it will deteriorate easily or
even lead to electric leakage. Sometimes this will result in change to the mechanical
performance of the materials and rusting of the metal components. If the relative
humidity is too low, the fastening screw will become loosen due to shrinkage of the
isolation spacer. In an environment with dry climate, static electricity may be produced,
putting the CMOS of the router to risk. High temperature is of the greatest risk: for it will
significantly degrade the router’s reliability, speed up aging process of the insulating
materials, and shorten the service life of the router. The requirements on the
temperature and humidity for AR 28 Series are shown in Table 3-1:
Table 3-1 Humidity requirements in the equipment room
Temperature
Relative humidity
5% to 90%, non-condensing
0°C to 40°C
3.1.2 Requirements on Cleanness
Dust is harmful to the safe operation of the Router. Dust on the chassis may result in
static absorption, thus causing poor contact of the metal connection components or
points. Especially under the condition of low indoor humidity, dust is easier to be
absorbed, which not only shortens the operational lifetime of the equipment, but also
results in communication failure.
There should not be explosive, conductive, magnetic and corrosive dust in the
equipment room where Quidway AR 28 Series Routers are located, and the dust
concentration should meet the following requirements:

Besides the dust specifications, the equipment room of the Router should also meet the
rigorous requirements for the content of salt, acid and sulfide. These harmful gases
could accelerate the metal erosion and aging process of some parts. The specific limits
of these harmful gases are given in the following table.

3.1.3 Requirements on Electrostatic Discharge Prevention
Although many antistatic considerations have been given to AR 28 Series, damage to
the router’s circuit or even the whole equipment may still happen when the static
electricity exceeds the tolerance threshold.
In the communication network to which the routers are connected, static induction
mainly comes from:
z
External electric fields such as outdoor high voltage power line or thunder.
z
Internal environment like flooring materials or the whole equipment structure.
Thus, the following should be considered to safeguard the equipment against the ESD:
z
Make sure that the equipment and the floor are well grounded.
z
Make sure that dust-proof measures are taken.
z
Maintain an appropriate humidity and temperature.
z
Wear an ESD-preventive wrist strap and uniform when contacting the circuit
board.
z
Place the uninstalled circuit board on the antistatic workbench, with its face
upward, or put it into the static shielding bag.
z
When observing or removing the uninstalled circuit board, please touch the edge
of the circuit board, and avoid contacting the devices on it.

Chapter 3 Installation Preparation
3.1.4 Requirements on Electromagnetic Environment
The interference sources, no matter where they come from, affect the routers with
capacitance coupling, inductance coupling, radiation of electromagnetic wave,
common impedance (including the grounding system) or conducting line (power line,
signal line and transmission line etc.).
So the following should be considered:
z
Take effective measures to prevent the power system from being interfered with by
the power grid system.
z
Keep the router far away from the radio launcher, radar launcher, and
high-frequency devices working in high current.
z
Use electromagnetic shielding when necessary.
3.1.5 Requirements on Preventing Lightning
Although many measures have been taken to protect AR 28-30/28-31/28-40/28-80
Series from lightning, if the lightning intensity exceeds a certain range, damage to the
router may still happen. To protect the router from lightning better, the following should
be considered:
z
Ensure the PGND wire of the chassis is well grounded.
z
Ensure the ground point of the socket of AC power supply is well grounded.
z
To enhance the lightning protection capability of the power supply, a lightning
arrester could be installed at the input end of the power supply.
z
As for the signal line outdoors to which the interface modules of AR 28 Series
routers are connected, such as ISDN line, telephone line, E1/T1 line, etc, a special
lightning arrester should be installed at the input end of the signal line to enhance
the lightning protection capability.
3.1.6 Requirements on Workbench
No matter whether you are to install the router in the cabinet or directly place it on the
workbench, it is necessary to ensure that:
z
There is spacing reserved at the air inlet and outlet in the router so as to facilitate
the radiation of the router cabinet.
z
The cabinet and workbench have good radiation systems.
z
The cabinet and the workbench are firm enough to support the router and other
installation accessories.
z
The cabinet and workbench are well grounded.

Quidway AR 28 Series Routers Installation Manual
Chapter 4 Installation of the Router
The power input end of Quidway AR 28 Series Router is connected to a noise filter. The
neutral point of the noise filter is directly connected to the chassis and is called
protection ground (PGND). The PGND wire must be well grounded, so as to safely
conduct the faradism and leaky electricity to the earth ground, and thereby improve the
capability of the whole device to guard against the electromagnetic interference. This
PGND wire can also protect the router against the lightning caused by the connection
with the external network lines, such as E1/T1 line, ISDN/PSTN line.
The grounding screw of Quidway AR 28 Series Router, which is marked with grounding
label, is located near the AC power socket and its switch on the rear pannel of the
chassis, as shown in the following figure:
(1)

2) AC input
3) Grounding terminal
Figure 4-3 Grounding screw of the router
Use a PGND wire to connect the screw to the earth ground, and the grounding
resistance should not be greater than 5-ohm. Likewise, if the router is installed in a
19-inch standard rack, this rack is required to be grounded too.
Caution:
When the router is in normal operation, it is required to be well grounded. Otherwise,
the router cannot reliably avoid lightning, which may damage the router itself and even
the peer device.

Synchronous/Asynchronous serial interface can work in either synchronous or
asynchronous mode. Different signaling standards are supported in these two modes.
V.35, V.24 (RS232), RS449, X.21, and EIA-530 support synchronous operating mode,
while V.24 (RS232) supports asynchronous operating mode. The maximum
transmission distance and baud rate of the signal vary with the operating mode.

Chapter 4 Installation of the Router
Caution:
The baud rate should not exceed 64kbps when the V.24 cable operates in synchronous
mode.
z
DTE and DCE
Synchronous serial interface can operate in both DTE and DCE mode. For two devices
connected directly, one should operate in DTE mode, and the other should operate in
DCE mode. The device at the DCE side provides a synchronous clock and specifies the
transmission rate, while the device at the DTE side accepts the synchronous clock and
communicates at the specified baud rate. Usually, the router serves as a DTE device.
To determine whether the device connected to the router is a DTE or DCE, please refer
to the manual that came with the device. Also the following table will be helpful in
identifying DTE and DCE. Usually, the PC or Router serves as a DTE device and the
Modem, Multiplexer or CSU/DSU serves as a DCE device.
In general, the asynchronous serial interface is connected to an external Modem or a
Terminal Adapter (TA) to work as the dial-up interface. In this case, it is unnecessary to
determine whether the device is DTE or DCE, and just choose an appropriate baud
rate.
For the operating mode configuration of the synchronous/asynchronous serial interface,
please refer to VRP3.4 Operation Manual.
2)
Synchronous/asynchronous serial interface cable
The WAN interface of the router (except for the AR28-12) is a DB-50 receptacle. Proper
connection cable needs to be selected for the protocol applied. By far, four types of
synchronous/asynchronous serial interface cables are available. At one end of these
four types of cables is a DB-50 connector, and at the other end (network end) is a
connector that can be one of the following depending on cable type:
z
V.24 (RS232) DTE cable: DB-25 (male) connector
z
V.24 (RS232) DCE cable: DB-25 (female) connector
z
V.35 DTE cable: 34PIN (male) connector
z
V.35 DCE cable: 34PIN (female) connector

5.2 Configuration Fundamentals of the Router
5.2.1 Basic Configuration Steps
In general, the configuration steps are as follows:
Step 1: Before configuring the router, the networking requirements should be made
specific, which include networking purpose, the role of the router in the network, the
division of subnets, WAN type and transmission medium, the network security policy
and reliability.
Step 2: Based on the above requirements, draw a clear and integrated networking
diagram.
Step 3: Configure the WAN interface of the router. First, configure the physical
operating parameters (e.g., the operating mode of the serial interface, baud rate and
synchronous clock) of the interface according to the transmission medium of the WAN.
For the dial-up interface, the user also needs to configure DCC parameters. Then,
configure the link layer protocol encapsulated on the interface and the related operating
parameters according to the WAN type.
Huawei Technologies Proprietary

Quidway AR 28 Series Routers Installation Manual
Chapter 5 Startup and Configuration of the Router
Step 4: Configure the IP addresses or IPX network numbers of all the interfaces on the
router according to the division of the subnets.
Step 5: Configure the routes. If it is necessary to enable a dynamic routing protocol, the
user should configure the related operating parameters of the protocol.
Step 6: If special security is required, perform the security configuration for the router.
Step 7: If special reliability is required, perform the reliability configuration for the router.
Please see VRP3.4 Operation Manual for the configuration details of the protocols or
functions of the router.
5.2.2 Command Line Interface
I. Characteristics of the command line interface
The command line interface of Quidway AR 28 Series Routers provides a number of
configuration commands, which can be used to configure and manage the router. The
command line interface has the following characteristics:
z
Performs the local configuration through CON port.
z
Performs the local or remote configuration through telnet command, which can be
used to directly log on and manage other routers.
z
Users can enter ? anytime to get online help.
z
Provides network diagnostic tools, such as Tracert and Ping, to quickly diagnose
the availability of the network.
z
Provides all kinds of detailed debugging information to diagnose network faults.
z
The command line interpreter adopts fuzzy search for the keywords of the
command. If the user enters the conflict-free keyword for a command, the
command will be interpreted accordingly. For example, for a display command,
the user can just enter dis.
II. Command line interface
The command line interface of Quidway AR 28 Series routers provides plenty of
configuration commands. Hierarchical user protection is adopted to prevent
unauthorized users from illegal invading. Each group corresponds to a view (please
see VRP3 Operation Manual for details). The user can use these commands to switch
between different configuration views. In general, only certain commands can be
executed under a particular view. But some common commands (such as ping,
display current-configuration, interface) can be executed in all views.

are available from Flash memory. If the router fails to boot with the secure boot file, it
prompts the boot failure.
The following table gives default names and types of boot files.
Table 6-1 Default names and types of the boot files
Boot file
File name
File type
Main boot file
main.bin
M
Backup boot file
backup.bin
B
Secure boot file
secure.bin
S
Note that:
z
The application images for system boot can be type M, B and S, but not type N/A.
You can store them in Flash memory, but only one for each. For example, if an
M+B file exists, it is impossible to have another M or B file. If you change the file
type of another file to B, the M+B file becomes a type M file.
z
You can modify the file name of an application image in Flash memory using the
command after it boots.
z
You cannot modify the file type of a type S application image file, but you can
modify the file type of type M/B and N/A application image files in the Boot ROM
menu or using commands after the application image boots.
z
Secure boot file is the last resort for system boot. You can download it in the Boot
ROM menu and must name it secure.bin. However, you cannot modify this file or
change the type of another file to S. If you change the name of the secure boot file
with the rename command after the system boots, the file is removed from Flash
memory. To use the secure boot file after that, you need to download it again.
z
The name (including the extension) assigned to a boot file is recommended to be
less than 16 characters.

interface. On the AR 28-09/28-10/28-11/28-12/28-13/28-14/28-30/28-31, this interface
must be Ethernet 0/0, the first fixed Ethernet interface. On the AR 28-40/28-80, this
interface is the first detected Ethernet interface, for example, Ethernet 1/0, the first
Ethernet interface in SLOT 1 in case no Ethernet interface module is installed in SLOT
0.
Caution:
No TFTP/FTP Server is available with the AR 28 series. You must install one yourself.

please contact the agent of Huawei Technologies Co., Ltd. With his consent, open the
chassis to check whether the SDRAM has become loose. If that is the case, you may
remove and reinstall the SDRAM. For the operation method, please refer to Section 6.2
“Hardware Maintenance” in this manual.
II. Troubleshooting of repeated reboot
Symptom:
z
After the information “Now testing memory...” appears, the system restarts
repeatedly. Or,
z
After displaying the information “System now is Starting ...”, the system restarts
repeatedly, and sometimes gives a prompt message “Copied program error.”
Solution:
Generally, such faults are caused by the damage to SDRAM. If the SDRAM is seriously
damaged, the problem will be found while testing the memory, and the system will
reboot. If the SDRAM is slightly damaged, the problem will be found during the process
of system starting, and the system will reboot, giving the prompt message “Copied
program error”.
Normally, the symptom is present when the SDRAM is damaged. If the damage is
serious, the router can find it when testing memory and reboot as the result. If the
damage is not serious, the router can find
If the SDRAM is damaged, replace it with a new one (before opening the chassis,
contact your agent for permission). For the replacing procedure, refer to Section 6.2
“Maintain the Hardware” in this manual.

7.4 Troubleshooting Application Software Upgrade
Symptom:
When upgrading the VRP software using the TFTP approach, the system displays the
following message:
Starting the TFTP download...
Then the router reboots automatically.
Perform the display version command; then you can see that software verison does
not upgrade.
Solution:
The symptom described above means that the new software version does not load.
Do the following:
z
Check the TFTP server to see whether information can be sent. If not, the problem
is likely to result from an incorrectly-configured TFTP server IP address. In this
case, make sure that IP address of the TFTP server is the IP address of the
network interface on the PC, to which the Ethernet interface is connected. (For the
procedure of selecting an Ethernet interface for TFTP upgrade on AR 28 Series
Routers, refer to section 6.1.2 IV. “Upgrading the application image through
Ethernet.”)
To check the IP address of a PC in a Windows environment, do the following:
In Windows 95/98/ME environment, perform the winipcfg command.
In Windows 2000/XP/2003 environment, perform the ipconfig command.
z
If Windows prompts IP address conflict, it is very likely that the IP address of the
TFTP server was incorrectly assigned to the upgrading Ethernet interface on the
Router.
z
Check the TFTP server. If it prompts a file locating failure, check whether the path
set on the TFTP server and the file name (including the extension) of the
application software set on the router are correct.
Upgrade the application software again after solving the problem.
Symptom:
When upgrading the VRP software using the TFTP approach, and the system displays
the following message:
Loading...
NET download completed...
read len = [05567609]
The downloaded software is not a valid version.
Please download the correct version.
Press <Enter> key when ready.

Quidway AR 28 Series Routers Installation Manual
Chapter 7 Troubleshooting
Solution:
AR 28 Series Routers should be loaded with different application software versions.
The problem described above is likely to result from a mismatch between the
application software version and the router model. In this case, contact your agent to
obtain the correct software version and upgrade it again.
If the improper software has been loaded, the Router cannot start or work correctly. In
this case, select Xmodem or TFTP mode in the boot menu to restore/upgrade the
software version (FTP upgrade mode cannot be used here).
If similar symptoms present when upgrading the software with other approaches, solve
the problem with reference to this example.
Note:
The bar code labeled on the Router host and the MIM contains the relevant
manufacturing and maintenance information. If you want to repair the device, inform
your agent of the bar code on the problem device.
